You will find the weekly IRC meeting an entertaining exercise in open development.
Questions (check all that apply :-) ) - Are you interested because of the slavish adherence to standards (as represented by GeoAPI interface?) - Are you interested because of the License LGPL - Are you interested in implementations that actually exist (ie coordinate reference system, rendering, etc...) - Have we met needs in terms of intellectual property protection; we have done an IP review; but have not yet completed the OSGeo incubation process - Is access to the developer community the important part - None of the above GeoTools is seeing an upswing of use lately and I am trying to determine the cause (and what we can do to keep the momentum going). > We are a company working basically on environmental informatics and > geodata processing, and we have two applications for which Geotools is a > strong candidate to be used within. The first one, which I am involved > in, is a desktop application to display satellite orbits and > corresponding swaths of instruments onboard these satellites. The > display will basically be a visualization of the orbits/swaths on a > world map, but shall be highly configurable in detail. E.g., we will > have to: > You may be interested in the http://udig.refractions.net/ platform; it is a desktop GIS framework built on GeoTools (and Eclipse); a UN group has already started a environmental informatics application with it called DivaGIS (and they have lots of fun stats work based on R hooked up already). > - display additional layers (e.g., a grid, country borders, cities, > selected zones, a background image) on demand > - supply mechanisms to zoom, rotate, shift, and to select specific > sections of the map > - show the map under different projections > GeoTools has the "chops" on the GIS side of things; you can use WMS to fetch background information (or GridCoverage directly for local information); but I must stress that we are not a "framework" for building a GIS. As a toolkit we can get you the data, and even draw you a picture - but interaction is up to you. The toolkit is also used on server only applications. There is so much to do in the world we have been forced to specialize and focus on the hard science / specifications end of things. > The last point is important regarding our potential contribution to > Geotools. Besides a "standard" rectangular cylindric projection, we will > need at least an AzimuthalEquidistant and a Gnomonic projection which > are obviously not yet supplied by Geotools (package org > <javascript:searchRef('org')>.geotools > <javascript:searchRef('geotools')>.referencing > <javascript:searchRef('referencing')>.operation > <javascript:searchRef('operation')>.projection). > <javascript:searchRef('projection')> Therefore, we will have to go and > add these projections following your tutorial > (http://docs.codehaus.org/display/GEOTOOLS/How+to+add+new+projections). > - You may also regard this email as "step 0" of that tutorial ;-) > Sweet :-) > Questions we may have in future will regard these projection topics, but > also the rendering and performance issues, which are also very important > for us. > There is lots of room for improvement in rendering and performance; an extra set of hands with a profiler is always welcome. You may also wish to review the uDig codebase which wraps the GeoTools rendering system in order to isolate some rendering paths for optimization (as an example shape files are rendered directly).
